90 are arranged symmetrically and the inner part 7 of the beam member 75
5a is formed in a C-shape in cross section and an outer portion 75b
Are formed hollow.

FIG. 10 shows the above cases 1a, 1b, 1
3C shows a drain pan 96 provided below (see FIG. 2). A concave portion 97 is formed in the center of the drain pan 96, and a large amount of dew water dropped from a cold water coil or the like is received in the concave portion 97. Reference numeral 98 denotes a drain pipe.

The above configuration can be further modified as follows. The casing 1 may be integrally formed instead of the three cases illustrated above,
It is also possible to configure with two cases or with four or more cases. The door may be omitted, and the entire surface of the frame may be covered with a screw-on panel. The synthetic resin that fills the panel space P between the outer frame 71 and the covers 72 and 73 may be another type of resin instead of urethane. Further, an outer wall panel may be configured by mounting glass wool in the panel space P.

The lip 90 may be made of hard resin instead of soft resin. Instead of the two lips 90, three or more lips 90 may be provided. The covers 72 and 73 can be made of synthetic resin instead of steel plates. The air conditioner to which the outer wall panel of the present invention is applied may be another type of device such as a ceiling-mounted type, instead of a floor-standing type.

【effect】

(Invention of claim 1) The invention of claim 1 has the following effects.
Since a plurality of skirt-shaped lips are integrally protruded from the outer frame made of synthetic resin, the above-mentioned plurality of lips can be elastically brought into contact with the frame by attaching the outer wall panel to the frame. Was. For this reason, even if the outer wall panel is distorted, it is possible to eliminate a gap between the outer wall panel and the frame, and the performance of maintaining the airtightness by the outer wall panel is enhanced. Moreover,
Since the lip is formed integrally with the outer frame, the production is less troublesome and the appearance is improved as compared with the case where the lip is fitted or adhered to the main body of the outer frame.

In the case of an air conditioner in which a pressure difference is generated between the inside and outside of the casing, the lip can be brought into close contact with the frame by utilizing the pressure difference between inside and outside, so that the airtight state can be maintained more reliably. Moreover, since a plurality of the lips are provided, it is possible to cope with any of the positive pressure and the negative pressure in the casing.

(Invention of claim 2) The invention of claim 2 has the following effects. Since the pair of lips are formed so as to be separated from each other as they approach the protruding end, in a state where the lips are elastically brought into contact with the frame, a relatively large amount of space is provided between the pair of lips and the frame. A large airtight space can be formed. The airtight space also improves heat insulation performance and soundproof performance. In addition, since the above-described effects can be achieved by a simple configuration in which a pair of lips are provided, the manufacturing cost can be reduced.

(Invention of claim 3) The invention of claim 3 has the following effects. Since the lip is made of a soft resin, the lip can be more reliably elastically contacted with the frame, and the performance of airtightness is further enhanced. In addition, since the soft resin lip is integrally formed with the hard resin body, the manufacturing cost can be reduced.
